ifstream infile(path);//以输入方式打开文件
string words[1000][2];//定义一个二维数组存储信息

/*
*此处为二分查找并删除的功能代码
**/
string biword = Binary_delete(insertword,words,0,counterNum-1);
ofstream outfile(path);//以输出方式打开文件
if(biword=="删除成功") counterNum--;
if(biword=="删除成功!") counterNum=counterNum-1;
for(int line=0;line {

outfile< }
outfile.close();//关闭文件
char* st = new char[50];
char *a = &biword[0];
strcpy(st,a);
*s=st;
}

这是C#写的界面：

代码如下：

[csharp]
using System;

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace InterFace
{
public class CPPDLL
{
[System.Runtime.InteropServices.DllImport("CSharpInvokeCPP.CPPDemo.dll", CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall, CharSet = System.Runtime.InteropServices.CharSet.Ansi, EntryPoint = "Add")]
public static extern void Add(ref IntPtr s, string y);
[System.Runtime.InteropServices.DllImport("CSharpInvokeCPP.CPPDemo.dll", CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall, CharSet = System.Runtime.InteropServices.CharSet.Ansi, EntryPoint = "txtReader")]
public static extern void txtReader(ref IntPtr s, string word);
[System.Runtime.InteropServices.DllImport("CSharpInvokeCPP.CPPDemo.dll", CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall, CharSet = System.Runtime.InteropServices.CharSet.Ansi, EntryPoint = "deleteword")]
public static extern void deleteword(ref IntPtr s, string word);
}
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)//添加
{
try
{
string word = textBox1.Text;
string wordCh = textBox3.Text;
if (word.Length == 0 || wordCh.Length == 0) MessageBox.Show("输入的中文和英文都不能是空!");
else
{
word = word + " " + wordCh;
IntPtr s = Marshal.StringToHGlobalAnsi("");
CPPDLL.Add(ref s, word);
string cstr = Marshal.PtrToStringAnsi(s);//得到值
textBox2.Text = cstr;
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

private
